BALING-MACHINE Specification of Letters Patent.

Application filed November 4, 1907. Serial No. 400,612.

To all whom it may concern:

Be it known that we, RICHARD A. CAswELL, CHARLES H. CAswELL, and WALLACECAswELL, citizens of the United States, residing at Cherokee, county ofCherokee, State of Iowa, have invented certain new and usefulImprovements in Baling-Machines; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The invention relates to presses for baling hay, straw, and the like, inwhich the compression of the material is effected by means of arcciprocatory plunger and the tying or wiring of the bale isaccomplished automatically by apparatus which feeds the wire around thebale, loops the ends thereof together and twist-s the looped ends, andfinally severs the wire adjacent to the looped tie, after which thefinished bale is discharged from the compression chamber.

The invention consists of the novel features and details of constructionand operation fully described in the following specification and setforth in the claims appended thereto.

In the accompanying drawings: Figure 1 is a plan view of the machine,with certain portions thereof broken away. Fig. 2 is a side elevationthereof; Fig. 3 is a fragmentary plan View of the carriage on the wiretying side of the machine with the tying mechanism removed; Fig. l is aside elevation of the mechanism shown in Fig. 3; Fig. 5 is a sideelevation of the duplex needle; Fig. (3 is an enlarged fragmentaryperspective detail showing the cooperation of the rack bar and the guidetherefor; Fig. 7 is an enlarged fragmentary plan view, partly 'insection, of one of the needles; Fig. 8 is a transverse section of theneedle on line 8'% of Fig. 7; Fig. 9, is a transverse cross-sectionalview of the machine in the rear of the plunger; Fig. 10 is a sideelevation of the tying mechanism; Fig. 11 is a sectional elevationthereon on line 00-00 of Fig. 13; Fig. 12 is a similar view on line 1 2of Fig. 13; Fig. 13 is an elevation of the tying mechanism viewed fromthe opposite side to that shown in Fig. 10; Fig. 14 is a plan viewillustrating the cooperation of the looping mechanism and the needle;Figs.15, 16, 17, 18 and 1%) illustrate successive positions of the wirelooping mechanism; Figs. 20 and 21 are detail views of the loopingmechanism with the front plate removed; Figs. 22 and 23 are reverseviews of Figs. 20 and 21, respectively; Fig. 24: is a fragmentary edgeView of one of the looping members with the several parts thereofseparated to better illustrate the relation of the clamping and cuttingjaws; Fig. 25 is a fragmentary side elevation of the middle portion ofthe baling chamber showin the relation of the wire spools .and the neeclcs; Fig. 26 is an enlarged plan view of the plunger; Fig. 27illustrates a modified form of the'looping member with the front plateremoved; Fig. 28 illustrates the form of the complete tie; Fig. 29 is anenlarged detail of one of the twister heads.

Referring to the drawings, it will be noted that the machine comprises abaling chamher, which may be either of the continuous or box type, areciprocatory plunger operating longitudinally of the chamber tocompress successive charges of the material, which is fed into thechamber in the form of a bale, a carriage slidably mounted on the frameof the compression chamber and which is adapted to be connected with theplunger and to move therewith during the final compression stroke, wirefeeding apparatus mounted on the carriage on one side of the compressionchamber, and wire tying apparatus mounted on the carriage on theopposite side of said chamber, the complete reciprocation of thecarriage with the plunger during the final stroke of the lattereffecting the feeding of the wire through the forward face of theplunger and into engagement with the looping, twisting and cuttingdevices, which complete the tie and sever the wire, the final retractionof the plungerserving to return the carriage to its initial positionwhere it is disconnected from the plunger, and the apparatus is restoredto condition to receive material for the succeeding bale.

The baling chamber, which, in the particular form of the inventionillustrated, is of the continuous type, is formed as a rectangularbox-like structure having longitudinal angle iron corner pieces 1 alongthe lower edges, which form the foundation for the chamber and serve asguides or track-ways for the movable carriage which supports the tyingmechanism; top longitudinal angles 2, which are connected to the lowerangles 1 by uprights 1 and 1"; and suitable crossbraces 2 at top andbottom which complete the frame work; an inclosing top plate 2,

provided with a filling opening 3; side plates 8 and a bottom plate 3.It will be understood that, should the machine be employed as a boxpress, a suitable movable abutment would be provided at the dischargeend of the compression chamber, but inasmuch as we prefer to use themachine as a continuous press, as illustrated, in which each finishedbale is forced out by the next bale in course of formation, there isprovided an inclined run-way or chute 200 hinged to the discharge end ofthe compression chamber as at 201 (see Fig. 2). The inclined run-way,which may be adjusted bymeans of links 202, hinged at the upper rearwardcorners of the compression chamber and adjustably connected to thedischarge end of the chute j or run-way in anysuitable manner, serves todehver the bales onto a plle, table, or vehicle as desired.

The plunger, by means of which the compression of the materlal iseffected, comprises a rectangular frame 170 made to fit within thecompression chamber and slide along the bottom thereof, and is adaptedto be reciprocated by a suitable connecting rod 173 which, in turn, maybe operated either by hand or by power. The compression face 17 2 ofsaid plunger is provided with transverse recesses 171 adapted 'topermitthe passage of'the wire feeding needles, as will be hereinafter morepartlcularly explained.

Pivotally mounted in brackets182 on side members 179 of the plunger 170are two levers 180, each having a laterally projecting latch finger 181,which finger serves under appropriate conditions, hereinafter explained,to lock the plunger to the movable carriage to cause the latter to movewith the plunger, as will alsobe explained more particularlyhereinafter; The said levers 180 are connected at their forward ends bya toggle 183,the central pivot pin 181 of which projects upwardly and isadapted to be engaged by a' generally rectangular trlppin lever 185,said tripping lever being pivoted on the same axis as one of the levers180, and having a laterally extending actuating finger 186 near thepivotal point and provided with an elongated slot 187 at its other endin which pin 18s of the toggle 183 is engaged, so that, when said triplever is The movable carriage 30 comprises bot-- tom members 33extending below and transversely of the baling chamber, and are securedto the lower angle iron 1 thereof by means of Z-shaped brackets 3 1 topermit said carriage to be reeiprocatcd longitudinally of the balingchamber. The righthand side of said carriage is a generally rectangularframe work, 32, 33 mounted upon and connecting the bottom members 33into a rigid structure and also supporting a tablelike element 31 uponwhich the needle actuating mechanism is mounted, and the portion of thecarriage on the left-hand side of the baling chamber consists of asimple flat skeleton frame formed of the ends of bottom members andlongitudinal members 30, upon which the tying mechanism is adapted to besecured by bolts or other appropriate means.

The wire feeding needles 20, which in the present machine are two innumber, are preferably made as an integral structure of U-shape, havinglateral grooves 24, 25 on opposite sides thereof, which engage flangedguides 17 secured in horizontal position 011 the carriage 30, asindicated in Figs. 1 and 9, so as to admit of the reciprocation of theneedles transversely of the carriage and the baling chamber. The forwardend of each needle is provided with guide rollers 21 and 22 mounted uponpintles 2G and 27, which rollers serve to receive and guide the wirewhich is taken from two spools 55 mounted upon a suitable bracket at atone side of the baling chamber in ad ance of the carriage. The forwardend of each needle is cut away at 23 for a purpose to be hereinafterexplained. Guide sheaves 17 are mounted on the carriage adjacent to theneedles and serve to direct the wire to the needles and hold the same inproper relation to the needles as the latter advance across the balingchamber.

The mechanism for reciprocating the needles comprises a. bell-crank 15pivoted at 15 to the table 31 of the carriage 30, and connected to acentral bar 20 of the duplex needle by a link 19. A second bell-crank12, pivoted at 13 to the carriage top, is connected to bell-crank 15 ata point intermediate the ends of the longer arm thereof by a link 14,and said bell-crank 12 is in turn connected with the forward end of aknuckle-lever 10 having a rule or knucklejoint 10 midway its length andpivotally connected at 9 near the discharge end of the baling chamberand having at its forward end a detent or abutment 10, which is adaptedto be engaged by the long arm of the bell-crank 15 when the latte"assumes the position shown indotted lines in Fig. l, as the needlesreach the end of their forward stroke, thereby causing the knuckle-lever10 to swing outward at joint 10 and permit the needles to remainstationary until the short arm of the angle-lever 15 comes in contactwith a lug 9 on the baling chamber. It will be understood, of course,that this operation of the needles is effected when the carriage hasbeen positively connected with the plunger and moves therewith. Theinitial movement of the carriage serves to operate the system of leversto advance the needles across the table and through the baling chamberuntil the forward ends thereof lie adjacent the tying mechanism. henthis point is reached, lever 15 engages detent 10 on the end of theknuckle-lever 10, causing the latter to move outward at the joint 10 andthe operative connection between the needles and the system of levers isinterrupted, permitting the needles to remain stationary until the shortarm of the bell-crank 15 strikes detent 9 as the carriage continues toadvance, and this engagement between bell-crank 15 and detent 9', duringthe continued advance of the carriage, re-

tracts the needles to their original position.

As the carriage continues its advance, the end of the short arm of lever15 slips past lug 9 and allows the carriage to move to the end of itsforward stroke. During the return movement of the needles by the reverseoperation of bell-crank 15, all of the needle mechanism is restored toits original position, as shown in full lines in Fig. 1, except knucklelever 10 which continues to break outward at the joint 10" during thefurther advance movement of the carriage. After the carriage has reachedthe end of its forward stroke and starts on its return movement with theplunger, the knuckle lever 10 is gradually straightened, and when thecarriage reaches the end of its return stroke said lever has moved untilits two arms are in alinement, at which time spring 13, attached to oneend thereof and the table throws the joint 10 beyond the dead center anduntil the lever is arrested by an adjustable stop 12, thereby restoringall of the needle actuating mechanism to a proper relaticn for the nextstroke.

As indicated, the carriage remains stationary with respect to the balingchamber until it is operatively connected wlth the plunger, and suchconnection is not made until the final compression stroke of the plungerhas been begun. The plunger is connected with the table by means offingers 181 carried by the levers 180, hereinbefore explained, saidfingers 181 being moved outward by the mechanism provided for thispurpose into engagement with suitable orifices in the sides of themovable carriage adjacent to the sides of the baling chamber, the latterbeing slotted at 167 to permit the passage of looking fingers 181, andalso to allow the wire feeding needles to pass into operative relationwith the tying mechanism.

The tying mechanism, as hereinbefore explained, is mounted upon themovable carriage and is operated by the advance of the carriage toeffect the complete tying operation during the advance movement of thethe tying mechanism.

carriage and is rendered inoperative during the return stroke of thecarriage. The means for effecting the proper operation of the tyingmechanism consists of a bar 40 connected by bell-cranks 47 and 48,pivotally connected to the left-hand angle iron at the bottom of thebaling chamber, as more particularly illustrated in Figs. 3 and 4. Eachof said bell-cranks 47 and 48 is pivotally connected to said bar 40, andto an actuating bar 44, which latter is adapted to be movedlongitudinally of the baling chamber sufficiently to move the rack 40toward and from the baling chamber. When the bar 40 has been moved outfrom the baling chamber, as indicated in full lines in Fig. 3, threeracks 41, 42 and 43 carried thereby, are in position to engage theactuating gears on the tying mechanism, and when said bar 40 is movedtoward the baling chamber the racks thereon are out of the line oftravel of the gears which drive the tying mechanism. After the carriage30 has been connected to the plunger 107, and has been moved with theplunger to the point of the beginning of the forward stroke, shown infull lines in Fig. 3, a detent 49 on the carriage engages an angularportion 44 of the bar 44, and moves the latter rearwardly, therebycausing bellcranks 47 and 48 to swing rack bar 40 away from the balingchamber and into position to cause the racks 41, 42 and 43 to lie in thepath of movement of the actuating gears of As the carriage and theplunger approach the end of their forward stroke, a detent 45 on thecarriage 30 engages roller 45 mounted on connecting rod 44, and causesthe latter to move with the carriage, which has the effect of causingbell-cranks 47 and 48 to swing rack bar 40 toward the baling chamber tothe position indicated in dotted lines in Fig. 3, and out of the path ofthe movement of the gears of the tying mechanism. It will be observedthat, although two different devices are employed for effecting themovements of the connecting rod 44 in the respective directions, eitherdevice might be duplicated, and obviously any other appropriate meansfor effecting the movement of said connecting rod 44 might be employed.The rack bar 40 is provided with U -shaped guides 4-6 attached near therespective ends of said bar, which guides embrace the lower flange ofthe angle 1 on the lower left-hand edge of the baling chamber and serveto retain the rack bar rigidly in position, but permit the bar to movefreely toward and from the baling chamber. In order that the rack barmay be held securely in alinementto mesh with the gears of the tyingmechanism during the forward stroke of the carriage, there is providedon the carriage a bracket 37 with a slot 36 in the end thereof, which isadapted to be engaged by a rib 35 on the underside one end thereofpasses beyond the slotted end 36 of bracket 37 when the carriage reachesthe end of its forward stroke to permit'the rack bar to be swung towardthe baling chamber and the other end of said rib to pass into alinementwith said slot when the carriage has been returned to the limit of itsrearward movement.

The mechanism for effecting the tying operation is duplicated in themachine illustrated, and therefore it will be necessary to explain butone of the devices. The tying mechanism is mounted upon a base 100,which is adapted to be bolted to the portion of the carriage 30 whichextends outwardly on the left-hand side of the baling chamber, and onsaid base there are provided posts or brackets 101, 102, 103, 104 and105 which support the various parts of the tying mechanism. Each of thewire tying mechanisms comprises a rotary clamping head which is adaptedto loop the ends of the wire to be secured together about a central pin,and a rotary twisting head which includes said pin together withappropriate clamping devices for holding the looped wire on oppositesides of said pin. Each 'of said wire looping members consists of anannular plate 60 provided with two projecting lips or hooks zi /,0?disposed at diametrically opposite points of the circumference of saidplate, and having on its rearward periphery suitable gear teeth 72 bymeans of which said plate may be rotated upon a central hollow journalor sleeve 107 fixed to standard 102. Adjacent to thehook members w, w,the plate 60 is provided with clamping faces a, a, as shown in Fig. 24.Cooperating with saiddisk 60 are'two annular disks/or plates '61 and 62,which are formed precisely alike but are reversely arranged with respectto each other. Said two plates 61 and 62 are likewise mounted on thesleeve-like trunnion and are retained in generally concentricarrangement with plate 60 by means of a 'front retaining plate 63 alsomounted on trunnion 107. Each of said members 61 and 62 is cut awaycircumferentially for sub stantially 180 degrees, thereby providing oneach two shoulders, which are adapted to be brought alternately inengagement, as

'indicated in Figs. 20 and 21, to wit, a

shoulder g on member 61 which is provided with a lateral clamping face6, cooperates with the clamping face 0; adjacent the hook m on member60, and a shearing edge 0 adapted to cooperate with the edge (Z of theshoulder 2 on 62. Similar clamping and shearing elements are disposed onthe plates at diametrically opposite points and are so related that,when the wire is sheared between jaws y, z,*it is released by thejaws w,y, and when the wire is sheared between jaws y, 2, it is released byjaws a2, y, that is to say, when the jaw 3 closes upon the jaw 00, theshear 2 2 opens, and similarly when jaw closes on m, shear w, y opens.It will be noted that, in order to effect an absolute homologousarrangement of the clamping and shearing elements of plates 61 and 62,the jaws y and a on 62 and 61, respectively, are offset, as indicated inFigs. 20 and 21, so that the jaw opposite y on plate 61 is z, and thejaw opposite 2 on plate 62 is y, and the two plates are so connectedthat, when the jaws g and 2 are fully separated, the opposite jaws g/and z are completely closed upon each other. The means for effecting therelative movement of plates 60, 61 and 62 consists of duplicate sets oflevcr mechanism for connecting plate 60 with plates 61 and 62,respectively, and more particularly illustrated in Figs. 10, 22 and 23.Mounted on the rear face of the plate 60 is a bellcrank 68, one end ofwhich normally projects beyond the edge of plate 60, and the other endof which is pivotally connected at 67 with a link 66 which, in turn, isconnected at its opposite end by a pin which passes through a slot 64 inplate 60, and is connected to plate 61 so that, as said bell crank leveris moved in one direction or the other, plate 61 will be movedcorrespondingly with respect to plate 60 and plate 62. A preciselysimilar arrangement of actuating means for disk 62 is locateddiametrically opposite that just described, and consists of a bell-crank90 pivoted at 92 to a link 92, which has at its free end a pin 94passing through a slot 93 in plate 60 and attached to disk 62, so thatthe latter is moved with respect to plates 60 and 61, in accordance withthe movement of bell-crank 90. The face plate 63'is notched atdiametrically opposite points in order to hold the ends of the wires andin a measure relieve the clamping jaws from the strain imposed thereonduring the looping and twisting operations.

Mounted on the standard 102 are two dogs 69 pivoted upon studs 69', theforward ends of which lie in the path of movement of the projecting endsof bell-cranks 68 and 90, as the looping heads are revolved, and serveto move the bell-cranks in a clockwise direction, as viewed in Fig. 10.Each of said dogs 69 engages a stop 70, and is normally held against thesame by a spring 71 attached to its free end and anchored to thestandard 102. It will be noted that this arrangement of the dogs willpermit the bellcranks 68 and 90 to pass freely withoutmoving, as thelooping heads move in a reverse direction. To effect the oppositemovement of bell-cranks 68 and 90 on the looping heads, there aremounted on standard 101 two spring held dogs 86, which are reverselyarranged with respect to dog 60 and serve to move bell-cranks 68 and 90in the opposite direction to which they were moved by the dog 69, aswill be apparent from an inspection of Figs. 10 and 13. Each of theplates 60 of the twister heads is provided with a gear rim 72 on itsrear face, and between said gears there is disposed an idle pinion 73.The gear rim 72 on the lower twister head is engaged by a pinion 74mounted upon a shaft 74 supported in standard 102, which gear 74meshesfwith a gear 78 mounted upon the shaft 7 8, on the outer end ofwhich is a pinion 85 adapted to be brought into mesh with racks 42 and43, respectively, on bar 40.v In order to hold the twister heads inproper relation, gear 78 is provided with a notched rim 79 with whichcotiperates a bowl or traveler 76 mounted upon a pivoted arm 74 andnormally held in engagement with the rim 79 by a suitable spring 80. Theengagement of the bowl or traveler 76 with one of the recesses in therim 79 is sufficient to prevent the gear train being accidentallydisplaced but does. not interfere with the proper operation of themechanism, and during the rotation of gear 78 the bowl travels upon thecircular portion of the rim but immediately drops into the appropriaterecess and locks the gearing when the movement of the looper heads hasbeen completed.

The mechanism for twisting the wire behind the engaging loops comprisesa twisting head associated with suitable clamping jaws, which head andjaws are located centrally within the looping head, and said twistinghead is mounted for rotation upon an axis at right angles to the axis ofrotation of the looping head, means being provided for operating thetwisting head and also for advancing the same to operative position toengage the wire at appropriate times. The twisting heads in both of thetying mechanisms are identical, and it will be necessary to describeonly one of said heads. A generally U-shaped frame 111 is mounted forreciprocatory motion upon guides 106 on the standard 102, as indicatedin Fig. 10. The horizontal arms of frame 111 project into the sleeves ortrunnions 107 of the looper heads. J ournaled in the forward ends of thehorizontal members of frame 111 are twister heads 133, one for eachtying mechanism, each head comprising a rotatory member having atransverse groove or recess passing therethrough and provided with aspring pressed pin 134 supported in the body of said member andprojecting through the recess and beyond the periphery in a directiontransverse to the axis of rotation of said member, as more particularlyindicated in Fig. 29. One peripheral edge of said twister head isprovided with gear teeth with which cooperate two pinions 132 mounted inframe 111, each of said pinions being, engaged by an idler 131, thepurpose of duplicating pinions 132 being to insure a driving connectionfor twister heads 133 at all times, even when one of the said pinions132 lies opposite the cut-away or segmentally grooved portion of saidtwister head. The upper idler 131 is driven by a gear 130' mounted upona shaft 130 in frame 111, which in turn meshes with idler 135 mountedupon shaft 135, which latter is in engagement with a gear 130 mounted onshaft 139, said gear 130 also meshing with the lower pinion 131. Gear130 is provided with a rim 136 having therein a depression 136 adaptedto receive a bowl or traveler 136 mounted upon a lever 137 and subjectto spring 138 which serves to lock the gearing in proper position, aswill be well understood. Shaft 139 is pro vided with two universaljoints 139 and 139 with an intermediate coupling shaft 139', and theoutboard end isjournaled in bracket 105 secured to the base plate 100.Instead of the universal joints shown in shaft 139, the latter may beformed as a flexible shaft of any suitable type, and the purpose ofmaking said shaft flexible is to provide a satisfactory drivingconnection for gear 130 which operates the twister heads and permits theframe 111 to be reciprocated. Mounted on the end of shaft 139 is abeveled pinion 82 which meshes with a beveled gear 81, mounted upon ashaft 83 journaled in bracket 104 mounted on the base 100. On the outerend of shaft 83 is a small spur gear 84 which meshes with rack 41 underappropriate conditions and imparts motion through the train of gearingto the twister heads 133.

It will be understood that the twister heads 133 will be brought intooperation after the wires have been looped about central pins 134, asshown in Fig. 17, and to effect this the sliding frame 111 is advancedso as to bring the looped wires well within the recessed portions of therespective twister heads 133 and at the same time to actuate theclamping aws by means of which the wire is held on each side of the loopwhile the twister head is being operated. These clamping aws, which areclearly illustrated in Fig. 12, are duplicated in the twistingmechanisms, and each consists of a pair of fingers 140 pivotally mountedin the sleeve or trunnion 107 upon pintles 143, and each of said fingersis connected by knuckle-joints or levers 141 with frame 111, the ends ofthe knuckle-joints being connected to the fingers and to the frame bysuitable pintles 142 and 144, respectively, so that, as said frame is-'cated in Fig. 3.

' indicated, by the movement of frame 111 toward the looper head, andthis movement of said frame 111 is effected by the following mechanismPivotally-mounted at its center 110 upon the base plate is a horizontallever 110, having on one end thereof-a roller 112 which is adapted'toengage the end of the rack 12 011 rack bar 410, and at its opposite enda roller 112" which is adapted to engage an inclined lug .56 projectinglaterally from the frame or'support of rack 43 on rack bar 10, indi-Connected to said lever at one side of the center is a link 113, whichis operatively connected with a bellcrank 11 1 pivotally mounted on theframe at which is connected at its other end" 1 of link and levermechanism, it will be noted that, when lever 110 is swung in onedirection by the engagement of roller 112 with rack 12, frame 111 willbe moved inward toward the baling chamber, and conversely, when lever110 is moved in the opposite direction by the engagement of roller 112'1 with lug 56 on the under side of rack 43, the

said frame is retracted or moved away from the baling chamber and theclamplng aws "i 1 10, which were closed by the forward movement of frame111, are restored to open position, as indicated in Fig. 12. A spring122, connected to frame 111 and to standard 106, tends to h old theframe 111 in retracted i position and assists in restoring said frame tosuch position after it. has been advanced. In order to lock frame 111 atthe end of its forward movement, there is provided 011 the latter a stopor lug 124; against which link 121 strikes after said links and 121 have7 passed the dead center, as shown in dotted lineslin Fig. 12.

V Pivotally mounted adjacent each of the tying mechanisms on standard104:, as-indicated in Figs. 2, 10 and 13, are wire rollers or guides150, each of which is revolubly mounted upon fingers 151 which arepivoted to standard 104i upon pintles 152, respectively. A spring 153,connecting levers 151, with the standard 1041, tends to hold the leversand guide rollers in horizontal position, indicated in dotted lines inFig. 13. The forward end of each of said levers 151 is enlarged andcurved downwardly to form a guide finger 163 for the wire. Connected tothe lower end of the roller lever 151 is a bell-crank 159, which ispivoted at to standard'104, the free ends of said lever 159 extendingdownwardly and adapted to engage a stationary lug or bracket 166 onhottom flange l ef the baling chamber, as illustrated in Fig. 2, andalso to engage the end of rack 41 and move the guide rollers intohorizontal position. The upper lever 151 is connected to the standard104- by a toggle comprising members 1%, 156, to the central pin 155 ofwhich is pivoted a link 15S connected at its opposite ends to a pin 161mounted in bell-crank 159. A stop or detent 156, projecting fromstandard 104;, serves to limit the movement of the toggle 154-, 156,past the dead center and therefore to lock the two levers 151, and theirassociated roller guides 1.50.

Mounted adjacent each of the tying mechanisms is a curved wire guide164-, clearly shown in Fig. 13, each of which is supported by a bracket165 secured to standard 108, each of said brackets having also alaterally projecting finger 1641- which serves as a hori zontal guidefor the wire, as more particu larly illustrated in Figs. 15 to 16,inclusive. The lower bracket 165 also serves as a guide for rack 43 onrack bar -10, while the latter is in mesh with spur gear 85. Pivoted tothe sides of the baling chamber adjacent to the slots 167 therein, aredogs 168 which nor mally lie across the respective slots, but which areadapted to be moved upward by the wires as the latter are advanced bythe forward movement of the carriage, said dogs subsequently dropping totheir lower position where they are retained by suitable stops ordetents, as indicated, and to hold the wires back of them as they arestretched between the needles and the tying mechanism.

The operation of the apparatus, as hereinbefore described, issubstantially as follows: Preparatory to receiving the first charge ofhay or the like, the various parts of the machine occupy the relativepositions shown in full lines in Figs. 1 and 2. The baling wires 6 passfrom the spools 5 through the guide rollers 21 and 22 in the ends of theneedles across the baling chamber, behind the dogs 168, to the rearwardwire clamping aws on the rotary wire looping members, the position ofeach of said looping members being illustrated in Fig. 19. The hay orother material is placed in the chamber through the opening 3 in the topthereof, and the plunger 170 is advanced forcing the material againstthe wires which are forced toward the rear or discharge end of thechamber, the wires, of course, being paid out from the spoolsaccordingly. After a sutlicicnt number of charges have been placed inthe chamber and successively compressed to make a bale of the requiredsize, and when the plunger 170 reaches the position on its finalcompression stroke where needles 20 come opposite the grooves 171 in theface 172 of plunger 170, trip lever is actuated by means of finger 186,which may be enio o gaged by the hand of the operator, to straightentoggle 183 and thereby project fingers 181 on levers 180 laterally fromthe sides of the plunger and into engagement with suitable lockingorifices in the sides of the carriage 30 adjacent to the sides of thebaling chamber, which has the effect of look ing the carriage to theplunger and to cause the two elements to advance together during thefinal compression stroke of the plunger.

As hereinbefore explained the toggle is adapted to' be actuated to swinglevers 180 into and out of locking engagement with the carriage and saidtoggle is held in either of its extreme positions by spring 189. Thetrip lever 185 is connected to the central pivot pin 184 of the toggle,so that when said trip lever is moved in one direction or the other bythe hand of the operator, the toggle will either straighten out to movethe fingers 181 into position to engage the looking orifices in thesides of the carriage when said fingers come opposite said orifices, oron the other hand, said toggle will fold inwardly to retract fingers 181and disengage the plunger from the carriage. The first effect of theconjoint movement of the plunger and carriage is to cause the needles 20to be advanced across the baling chamber which carries the two strandsof the wire around the rear face of the bale and lays the same oppositethe hooks m on plates 60 of the wire looping heads, as indicated in Fig.14. The particular operation of advancing and returning the needles hasbeen fully set forth hereinbefore and need not be repeated, except tostate broadly that it is effected by the link and lever mechanism,particularly illustrated in Figs. 1 and 9.

In the normal position of the apparatus, shown in Figs. 1 and 2, rackbar 40 occupies the position shown in Fig. 3 with the racks 41, 42 and43 in position to be engaged by the spur gears on the tying mechanism.As soon as the needles complete their inner stroke so that their endslie adjacent the looping mechanism, as indicated in Fig. 14, spur gear85 passes into mesh with rack 42 which turns each of the looping headsthrough the trains which actuate the gear rims, 7272, on the rear ofplates 60 of the respective looper heads. Each looper head makes onecomplete revolution. The initial movement of each looper head causes thecorresponding finger w on plate 60 to pass through the cut-away portion23 of the corresponding needle behind the wire, and the further movementof the looper head causes bell-crank 68 to engage dog 69, whichstraightens out the knuckle-joint formed by link 66 on one end ofbell-crank 68, and rotates disk 61 a short distance and in oppositedirection to the movement of the looper head as a whole. This causes theclamping jaw 3 on plate 61 to close on w,

causing the clamping faces a and b on the respective plates to grip thewire and hold the same firmly in position. It will be understood, ofcourse, that the free end of the wire is held during this operation be-70 tween the corresponding clamping faces and jaws m, y, on thediametrically opposite side of the looper head, as indicated in Figs.

15 to 19, inclusive. As each looping head continues its revolution, therespective ends of the wire assume the several positions shown in Figs.15, 16 and 17, and until the jaws w, y, on the looper head return totheir initial position, as indicated in Fig. 17, when the wire has beenlooped twice about 0 central pin 134 on the twister head 133 and the twoloops are locked together, the guide roller 150 serving to properlydirect the wire from the corresponding needle to the periphery of thetwister head, and the finger 5 163 in advance of said roller serving tolay said wires in proper relation to cause the loops to interlock. Whenthe twister heads have made one complete,revolution, gear passes out ofengagement with rack 42, and at this point in the operation of themachine roller 112 on lever 110 strikes against the end of rack 42 andadvances frame 111, carrying the twister heads toward the baling chamberand at the same time closing fingers 140 of the clamping jaws over theloops of the wires which lie in the recessed portions or segmentalgrooves in the twister heads 133. The continued forward motion of thecarriage 30 brings gear 84 into mesh with rack 41, which actuates thetwister heads through the system of gearing, hereinbefore described,turning the twister heads 133 through the desired number of revolutions,in the present instance three, which eifectively twist the loops of thewires on themselves, as shown in Fig. 18. Roller 112 then engages lug 56below rack 43, which returns the frame 111, with the twisting apparatusto its initial position and releases the wires from the clamping jaws140, so that the knot or tie will slip ofl the end of the pin or finger134. At this time the spur gear 85 passes into mesh with rack 43, whichreverses the motion of the'wire loop- 115 ing heads through one-halfrevolution, as shown in Fig. 19. As soon as the looping head starts torevolve backward, bell-crank 90 engages dog 86. This breaks the knucklejoint formed by bell-crank 90 and link 92, and opens the jaw y and atthe same time moves the wire cutting edge (Z of shoulder a on plate 62into contact with the wire cut ting edge 0 on shoulder 7 of plate 61,which severs the wire between the clamping jaws 00, y and the knot, theneedle end of the wire being still retained in the jaws 00, y, so that,when the looper head has been revolved backward a complete halfrevolution, the hook w on plate 60 assumes the position &

previously occupied b y hook m. The needle end of the Wire still beingheld by the clamping jaws 0a, 1 and the carriage advancing to theforward end of its stroke, said needle end of the wire drops behind dogs168 in position to surround the forward end of the next charge. When thecarriage is returned to its starting point, the loose needle wire, whichwas wrapped around the outside of the looping member, is drawn into theposition shown in Fig. 19, and the jaws 0e, 3 stand open to receive thewire from the needle for the next bale.

After severing the wire behind the knot the carriageadvances to theextreme end of its forward travel, and detent 45 strikes roller 45 onbar 44' which moves the latter in the same direction that the carriageis moving, and by means of bell-cranks 47 and 48 shifts the rack bar 40toward the baling chamber and into the dotted position shown in Fig. 3.7 On the return stroke, while the carriage and plunger are stillconnected, it will be observed that the rack 40 is out of alinement.with the gears 011 the tying mechanism and that therefore the latterwill not 7 be operated. f-As the plunger and carriage approach the endof their rearward stroke, and the carriage reaches the positionindicated in Fig. 1, the plunger is disconnected from the carriageeither manually or by the automatic means shown in Fig. .25, but beforethe carriage comes to rest detent 49 thereon engages bar 44, moving thelatter rearwardly and shifting rack bar 40 through connected bell cranks47 and 48 outward from the baling chamber into the position shown infull lines in Fig. 3, and in proper alinement to mesh with the spurgears 84 and 85, which drive the looping and twisting mechanism,respectively. At the same time bell crank 159, engaging detent 166,

raises guide levers 151 to the position shown in dotted linesin Fig. 13.The apparatus is thus ready to receive the materialv for a new bale andthe operation described is repeated. Each bale, as it is completed, isforced onto the runway 200 which, of course, contains a number of bales,and the end bale on said runway is discharged upon a suitable receiver,as hereinbefore described.

The modified form of head, shown in Fig. 27, is essentially the same inprinciple and operation as that shown in Figs. 20 to 24, inclusive. Thehead consists of two similarplates, the front one of which is removed inFig. 27, the main or rear plate 906 alone being shown. Between theplates of 'the head are mounted two sets of wire clamping and wireshearing devices, which are precisely alikeand located-diametricallyopposite eaelf other on the head, and therefore the description of oneset of clamping and shearing devices will suffice for both. The hookmember Y is pivotally mounted on plate 906, at 905 and has a wireclamping face a which closes down on the outer face of the stationaryjaw X located 011 the back of the cutting member Z. The member Y alsohas a shearing edge 6 against which the cutting member Z acts. Themember Z is pivotally mounted on plate 900, at 908. Members Y and Z areconnected at 911 and 912 by link 901', and members Y and Z are connectedat 911 and 907 by link 901. The fingers 900 and 900 are pivotallymounted on the outside of the plate 906, and rigidly attached to shaft908, and lever 913 is also rigidly attached to said shaft and isconnected with the member Y by link 914.

The operation of the modified'form of the head is substantially asfollows: When the head is revolved in a clockwise direction, the finger900 engages the dog 902, which causes shaft 908 to rotate and thereby tooperate links 913, 914 to move the member Y inward until the face (1thereof engages the outer face of X to clamp the wire between the saidfaces. The opposite end of member Y moves outwardly or in the oppositedirection, which opens the shear Z. hen the head is revolved in theopposite direction, the finger 900 strikes the dog 902 which, actingthrough shaft 908 and links 913 and 914, moves the hook member Y in theopposite direction and causes clamping face a to pass out of engagementwith clamping face X. At the same time shear member Z is forced outwardand catching the wire between its edge and the shearing edge I) on Ysevers the wire.

The operation described applies to each set of shearing and clampingdevices and, when the jaw Y opens, the shear Z closes, and, when the jawY closes, the shear Z opens, and similarly, when jaw Y opens, the shearZ closes, and when jaw Y closes, shear Z opens, the respective jawsbeing closed when the head is revolved in a clock wise direction andopen when the revolution of the head is reversed.
